createVariable does not accept Dimension objects as dimension specifications

[zerothi]

It would be nice if the following could be done, for completeness sake:

import netCDF4 as nc

out = nc.Dataset("hello.nc", 'w')
dim = out.createDimension("size", 2)
foo = out.createVariable("foo", 'f4', ('size',))
bar = out.createVariable("bar", 'f4', (dim,))

The documentation is coherent with the implementation, but I think the above should be allowed.

Not obvious to me that this is necessary, but if someone's willing to implement this I'll entertain a PR.

This actually turned out to be pretty straightforward as well, so I went ahead and created a PR #1147

PR #1147 merged, closing now...
